Abstract

CABLE CLAMPS IN SOFT PLASTIC MATERIAL WITH HARD ELASTIC TIMING, CONSISTING OF A RELATIVELY LONG STRIP, EQUIPPED WITH A SERIES OF LOCKING NOTCHES, AS WELL AS A HEAD, MADE SOLIDARITY BY MOLDING THIS STRIP. IT IS PROVIDED ON HEAD 3 AT LEAST TWO ELASTICALLY COMPRESSIBLE RECESSING SNAPS 10, THROUGH THE OPENING HOLE 7 OF THE SUPPORT PLATE 8, AND WHICH ARE ANCHORABLE THEREIN. THE PRESENT INVENTION APPLIES IN PARTICULAR TO THE FIXING OF CABLE HARNESSES IN THE AUTOMOTIVE OR HOME APPLIANCE INDUSTRY.

Description

At 2 497012

  The present- ness starts from a cable tie of the type specified in the letter of the request for

  patent, and known for example from Vir the description of publica-

  29 46 258, FIGS. 7 and 8 in particular, and which is intended to grip a bundle of cables or elements of a similar nature.

  and fix them in position on a support plate.

  To do this, the free end of the strip is introduced into the hole provided for this purpose by the support plate, it is passed on the back around the bundle of cables to be fixed, then it is made to pass through the hole of the support plate and the opening of the head of the cleats and tighten. In this case, the cleat is supported by its flange on the edge of the through hole, while the cable bundle is applied.

on the other side against the plate.

  This method of fixing the cable clamp on its support plate is simpler and returns

  cheaper than, for example, rivet fastening to

  expandable (GB-PS 1079 888) or T-peg (DEAS 18 10 515). There is also not, on the side where is the wiring harness, bulky parts or elements protruding from the cable clamp. This method of fixing the cable clamp has the disadvantage

  that the cable clamp can only be put in place

  o the bundle of cables or similar elements to be fixed

  is positioned on the support plate, in front of the

  fixation. Unlike other cable ties mentioned,

  it is not possible to mount anything here to advance

  this. The subject of the present invention is therefore

  to improve the design of the cable tie described in the

  generic cept in such a proportion that it can be

  placed in the hole of the support plate independently of the pre-

  the cable harness to be fixed, so that the

  cable ties can be carried out in a chain of

  for example, separately, ie to another

  right at another moment in the operation of fixing the cables

in position.

  For the resolution of this objective, the configuration characteristics provided for in the characterization section of the main claim are provided,

  The particularities of the invention as well as the advantages that it presents on the technical plane

  of the following description of an exemplary embodiment of

  this one, as well as the claims and the board of

  diagrams of this description. The different illustrations represent respectively:

  Figure 1 - a longitudinal sectional view

  of a cable tie in the delivery condition, Figure 2 - the cable tie seen in plan,

  Figure 3 - a cross sectional view

  dirty in the head of the cable tie, and Figure 4 - a cable clamp mounted in position.

  The cable clamp shown in the diagrams

  mas that precedes is made of a plastic material with

  hard elastic band consisting essentially of a band (1) provided with a series of locking notches (2), and a head

  (3) made integral by molding one end of the ban-

  from 1). This head has an opening (4) intended to allow

  putting the introduction of the free end (5) of the band, and further a locking tongue (6) projecting inside the opening (4), tongue whose interaction with the locking notches (2) of the strip (1) in the insertion position in the opening is such that one can pull this strip (1) through this opening (4) in only one direction, any attempt to traction in the other direction

being immediately blocked.

  The head (3) of the cable tie is intended

  born, as shown in Figure 4, to be introduced into the hole (7) provided for this purpose in a support plate (8). The head (3) is provided for this purpose with a support flange (9) arranged transversely to the insertion direction of the strip, which is applied on the support plate (8)

  once the cable tie has been pulled into the hole (7).

  To be able to axially lock the head (3) in the hole <7) it comprises, besides the support flange (9) at least two resiliently compressible mounting lugs (10) 1 which pass through the trc (7) and that are dockable in this one

  and which are connected to. = support flange (9) via

  resilient elements such as for example a rod (II) dimensionally adapted to the diameter of the hole (Figures 3 and 4) This rod (11) serves to ensure the centering of the head (3) in

  the hole - (7) and thus confer on it, in conjunction with the

  support (9) a stable apex position on the

support plate (8).

  The embedding lugs (10) are in this case made by integral molding of the upper edge of the rod (11) at a distance from the bearing flange (9) such that after having passed through the hole (7), and that the support flange (9) is applied against the support plate (8), they relax by elastic return and fit on the

  rear part of this support plate. To facilitate the

  pressure of the mounting lugs (10) these comprise, on their front end, pressure introduction faces (12), which approach in a conical pattern (see FIG.

  3), and by which the mounting lugs (10) can be

  take precedence automatically when introduced into the hole (7).

  The cable tie corresponding to the example

  Embodiment of presently described embodiment comprises only two mounting lugs (10), diametrically opposed on the periphery of the rod (11). But it is possible to predict

  three mounting lugs or even more, if one con-

  this solution as presenting a practical opportunity

  only to obtain a better holding of the head (3) in the fixing hole (7). These mounting lugs can be

  molded directly from the col-

  lerette support by means of elastic arms, without

  that it is then necessary to provide rod (11).

  For reasons of practical

  that the locking tongue (6) is also made solid

  molding the upper part of the rod (11) and

  skewed obliquely in the direction of the introduction of the band

  (1) in the opening (4) under conditions such that its

  te (13) arrives at its end at the lower zone

  the rod (11) and the support flange (9). This provision

  The advantage of this is that on the insertion side of the support plate (8) only the support flange protrudes.

  (9), while the end of the strip (5), after

  duction, can be cut in outcrop of the plan of the glue-

  support ruler (9) as soon as the cable bundle to be fixed (14) is securely clamped in position by the band (1).

  The openings (15) and (16) that

  the support collar (9) are intended only for

  meet the requirements of demolding, and have no

  nothing to do with the operation of the head

  re-cables. Also the arched part (17) that the
